ADS1210U – TEXAS INSTRUMENTS

The Texas Instruments ADS1210U is a low-power, 24-bit delta-sigma analog-to-digital converter (ADC) housed in a 16-pin TSSOP package. It features a single-ended input, capable of operating from a ±2.5V supply voltage, though its input range is typically ±0.5V. The ADS1210U boasts a maximum sampling rate of 1000 SPS and achieves high resolution through its delta-sigma architecture, resulting in excellent linearity and low noise performance. Internal circuitry includes a programmable gain amplifier (PGA) with gains ranging from 1 to 128, allowing for flexible signal conditioning. The device communicates via a 3-wire SPI interface, simplifying integration into microcontroller-based systems._x000D_

Its low power consumption, typically under 1mA, makes it ideal for battery-powered applications requiring high-resolution data acquisition. Common use cases include biomedical instrumentation (e.g., ECG, EEG), industrial process monitoring, and precision weighing scales. A key advantage is its ability to achieve high resolution without requiring external components for signal conditioning in many applications, reducing board space and design complexity. The ADS1210U’s built-in PGA and internal reference further streamline the design process, making it a cost-effective and efficient solution for high-precision analog-to-digital conversion.
